JTech has spent thousands of hours engineering the best laser product on the market for industrial, enthusiast, and research applications. It is now here. We have redesigned the product to improve safety, stability, power, and more cutting ability. We have tested the laser for continuous use at full power for more than 5 days straight of use in normal operating conditions.
JTech has gone through many generations of the design to get to the best of the best. They have performed extensive thermal imaging and thermal analysis to get to a stable output at high power.
JTech new interlock system is totally re-designed to give optimal performance and safety you can depend on with extra features and more transient suppression. The isolated inputs are now even more industrial as well.

-Note: The beam is slightly rectangular. Focused size specification is for the long axis.
-Above specifications are for reference purposes only and are subject to change. Figures in specifications may contain measurement errors.
-Because it is running at 7W, the lifespan will be diminished. Running it at lower current will increase the lifespan.
We have kept all of the features that make this laser kit awesome – precision laser trimmed regulators for constant current to the laser, 0.01 tuning resolution, digital isolation, soft start, esd protection, current limiting, and the list goes on. But NOW we have more safety in mind as well! The US Federal Government has a list of things that are required for operating these high power class 4 lasers. They might seem trivial, but they could save your eyesight! Here is a run down of the safety features to protect yourself and others:
This is the fifth generation of the popular High Current Laser Diode Driver series. We designed this new generation to follow the federal guidelines for safety compliance for high power Class 4 laser operation. This includes the use of a key enable switch, safety interlock system, power off reset, and laser LED indicators. All of these features make for a safer laser operation and will comply with federal laws regulating such operations.
At the heart of the product are laser trimmed parallel regulators to give constant current without the large temperature dissipation of other regulators. Couple this with inherent safety features like soft starting, current isolation, reverse protection, ESD protection, and thermal shutdown control and you have all you need in a small package.
The high power laser diode driver is cost effective and easily integrated into industrial, research, or enthusiast projects and products. The driver can be operated in CW mode or in Input Control Mode to be interfaced to remote electronics. This design uses digital isolators for super fast response and input range while protecting the laser from deadly ground loops. The board has screw terminal connections as well as Molex mini-fit Jr. connectors for easy connections to external equipment for control and the laser diode output.
